Anyone know anything about this Operadio model 3313vc power amplifier.
Thought about modding it to use for guitar amp but it occured to me that it might have some value in it's original condition.

I'd just go ahead and mod it if Reverb is a bust. That mike is cool.

That's the stuff... it never tasted the same after the tree-huggers forced a formula change!

I still have an old can somewhere, probably could do with a good stir. Lol

Greg- That's an "Operation" basso (bassinet) type microphone you found, made by DuKrane...
Wish there was a web site you could still get outlawed cans of half used basso, etc, from! 8)

OP- Nice piece! I may have some original literature on it, I'll look and if I do,
I'll post on here to share.

I looked and couldn't find anything that old in my Operadio catalogs, only back to '37 and this unit predates it by a few years,
there's a similar (updated tube) model with a Bruno Velotron microphone included for $29.95...

I don't believe an amplifier with that low of output power would need any "mods" for modern use as an "ancient Champ amp" so to speak,
except perhaps a input adaptor for modern Hi-Z input.
I would replace all old paper and electrolytic caps, check and replace resistors and try it as is, you may be surprised how good it sounds
